To all whom it {Z'Luf/ concern Be it known that I, Lao Mannntsrarr, a citizen of the United States, residingatNew York, in the county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Treating Oils and the like; and I do hereby debe a full, clear, and

will enable others skilledin theart towhich it appertuins to make and use the same.

his invention relates" to improvements in apparatus for converting unsaturated fatty acids such as oleic acid, cottonseed oil and similar mixtures of unsaturated fatty acids into solid and semi-solid saturated com- 7 pounds.

,An object of my invention is to provide means for raising the. temperature of the oleic acid, cottonseed oil or similar mixtures of unsaturated fatty acids to. the desired de: gree and maintaining the same a Such a degree during the treatment.

A further object of my invention is to keep the oils or acids being treated agitated as well as the catalyzers used in said treat merit.

A further: object of my invention is to provide means for supplying hydrogen to the oil or acid beii'lg treated, said hydrogen gas being injected into said oil or acid so as to kee said 'oilvor acid agitated as well as a catalyscr therein. 1

Furtherobjects will be apparent from the following specification, appended claims and drawings, in which, p

Figure 1 is an elevation of my device, Fig. 2 is a sectional view through the cylinder with the hydrogen gas inlet pipes rellwved, and, Fig: 3 a similar view showing means. Each of the heads 11 and 12 is procylinder 10 to the hydrogen pump 37 10 may be drawn therefrom.

vided with a hand-hole 13 and threaded openings 14, 15, 16, 17 and 18.

(.nnmunicating through the openings 14 and 15 tothe head 12 from the inside of the oil pumps 19 and 20 are the pipes 21 and 29., each of which being provided with a check valve 23, said pipes terminating at the bottom of-the cylinder 10 so that, oil, or the contents of the said con- {diner maymhe drawn through said pipes by f the action of tlie pumpsfii and 25 in the cylinders 19 and 20 respectively.

Pipes 26 and 27 provided with check valves 26 and 27 are secured to the cylinders 19 and 20 respectively and pass through the openings 14- and 15,. of the head 11 and are provided with spraying nozzles 28 and 29 respectively so that the oil and the like drawn up by the pumps 2% and 25 in one direction of, their movement is forced through the pipes 26 and 27 in the reverse movement thereof, said oil and the like being sprayed through the nozzles 28 and 29 so as to make the some more susceptible to the treatment by hydrogen gas to be hereinafter described.

The cylinder 10 has a plurality of hydrogen gas Sprayers or distributors 30.some of which are secured to the vertical tubes 31 as by the tees 32, sufiiciently secured to the six way fitting 83 in the top of the "containcr, the horizontal nipples extending therefrom receive the bent ends of the upright pipes 31 and to the double sprayer 34 is secured a fitting 35 which in turn is secured at the lower curved end of the pipes The sprayer 34 spraying in all directions so accumulating in the bottom of the cylinder 10, the fitting 33 is suspended or carried by the lower end of a pipe 36 which passes through the head 11 and is secured to the Interposcd: between, the pipes 31 and the cylinder 10 is a steamcoil 38 the ends of which pass through the openings 15 in the heads 11 and 12 and from thence to the source of supply. The head 12 is provided with a drain valve 39 secured inthe opening 18 by which valve the contentsof the cylinder The threaded openings 17 of the hauls l1 and 12 may be provided with plugs O.

he operation of this apparatus is as follows: The cylinder 10 is filled to aboutfi of as to agitate'the cata-lyzer placed in the cylinder 10 and to prevent the same from its capacity with the oil to be treated and the catalyzer also placed therein, then the mixture of oil and catalyzer' is heated to 180 degrees C, and hydrogen gas is admitted through the nozzles 30 under pressure, then the'liquid is constantly agitated by means of the ingress of hydrogen gas and the pumps 24 and 25 until the oil is sufiici'ently acted upon. The contents of the cylinder 10 are heated to the desired temperature by the steamcoil 38. When the oil or acid is sufiiciently hydrogenized it is then treated with" caustic soda *to neutralize any free fatty acids remaining in theoil.

I amaware that various modifications may be made within the scope of my invention and I do not restrict myself to the identical form shown as the drawings submitted herewith are for illustrative purposes only.

Having thus described my invention, I-
